This article utilizes original survey and interview data to explore why norms governing lesbian, gay, bisexual, and transgender (LGBT) rights mobilize an active resistance in some cases and not in others. Based on a comparison of Poland and Slovenia, this article shows that differing perceptions of threat define the way international norms are received in distinct domestic realms. Threat perception is heightened in cases where religion is historically embedded in the essence of the popular nation. In Poland, the Catholic Church created a role for itself as a symbol of the nation. There, the domestic opposition succeeded in framing a narrative that linked LGBT rights to external forces threatening national values. By contrast, the Catholic Church in Slovenia could neither maintain nor (re-)establish similarly strong ties to the popular nation, stifling the opposition’s ability to mobilize a robust popular resistance. Whether resistance is effectual, however, is a related but separate question. The data suggest that resistance produced in high-threat contexts can be self-defeating in that it enhances the salience of the norm in the domestic setting.
